Novel vehicle-tail-gas purifying structure

Abstract

The invention discloses a novel vehicle-tail-gas purifying structure. The novel vehicle-tail-gas purifying structure comprises a shell, a gas inlet pipe is in threaded connection to the outer side ofone end of the shell, a gas outlet pipe is in threaded connection to the other end of the shell, a heat insulating layer is arranged on the inner surface of the shell, and two groups of guide plates are symmetrically arranged at the position, close to a pipe opening of the gas inlet pipe, of the inner side of the shell. According to the novel vehicle-tail-gas purifying structure, a crawler-type ceramic electric heater and a limiting base are arranged, a catalyst carrier is heated through the large contact area during paving, and the heating efficiency is improved; then an oxidation-reduction reaction occurs under the condition that the temperature is kept enough, organic matter in tail gas is completely decomposed, and the purifying effect is improved; the catalyst carrier is firmly clamped through the elasticity of springs, the fixing effect is better, the catalyst carrier is conveniently assemble and disassembled, the carrier is effectively protected and is not damaged, the service life of the carrier is prolonged, and the novel vehicle-tail-gas purifying structure is suitable for different working stations, and brings better application prospects.

Description

technical field [0001] The invention relates to the field of tail gas treatment, in particular to a novel automobile tail gas purification structure. Background technique [0002] Pollutants contained in automobile exhaust include solid suspended particles, carbon monoxide, carbon dioxide, hydrocarbons, nitrogen oxides, lead and sulfur oxides, etc. Therefore, it is necessary to filter and purify these pollutants during exhaust emission; the existing There are certain disadvantages in the use of the automobile exhaust purification structure. During the driving process of the automobile, the vibration generated is relatively large, and the continuous vibration will cause impact on the carrier inside the purification structure, which will reduce the service life of the carrier for a long time. At the same time, the existing Most of the purifiers do not have a heating structure or the thermal efficiency of the heating structure is low, resulting in insufficient purification of e...

[0002] Pollutants contained in automobile exhaust include solid suspended particles, carbon monoxide, carbon dioxide, hydrocarbons, nitrogen oxides, lead and sulfur oxides, etc. Therefore, these pollutants need to be filtered and purified when the exhaust gas is discharged; the existing There are certain disadvantages in the use of the automobile exhaust purification structure. During the driving process of the automobile, the vibration generated is relatively large, and the continuous vibration will cause impact on the carrier inside the purification structure, which will reduce the service life of the carrier for a long time. At the same time, the existing Most of the purifiers do not have a heating structure or the thermal efficiency of the heating structure is low, resulting in insufficient purification of exhaust gas, which has brought certain adverse effects during use. Therefore, we propose a new automobile exhaust gas purification structure
